Abstract:

The effects of important process parameters on mechanical response during the densification of an industrial food powder were investigated and important phenomena described using the power rule. The factors studied had highly significant effects on mechanical response. The effects of the models in predicting the behaviour of the system were also highly significant. The findings are of relevance to processing and handling of food powders.

Abstract:

A cohesive force at an adhesive bond is one of the limit for a strength of an adhesive bonding. This study is focused on an impact force of an adhesive. Samples without a notch were cast in the casting mould at a laboratory temperature with a normal pressure. The instrumentation microcharpy test equipment was used for the evaluation of the impact force. The samples were tempered at a laboratory temperature, 40 °C and 60 °C. Results showed that the temperature of the specimens influenced the impact strength, the toughness and the maximum deformation of the adhesives. Higher temperature decreased the impact force but it increased the toughness. The hardness Shore D of commercial filled two-component epoxies is comparable. A nonhomogeneity of adhesives distinguished for a porosity was found by the investigation of a fracture surface.
